I MPROVEMENT IN PYROTECHNIC CARTRIDGES.

Specification forming part of Letters Patent No. 217,115, dated July 1,1879; application tiled May 10, 1879. Y

To all whom lit may concern:

Beit known that I, EDWARD D. KENDALL, of Jersey City, in the county ofHudson and State of New Jersey, have invented certain new and usefulImprovements in Nautical Signal-Light Cartridges; and I do herebydeclare that the following is a full, clear, and exact description oftheinvention, which will enable others skilled in the art to which itappertainsy to make and use the same, reference being had totheaccompanying drawing, and to the letters of reference marked thereon,which forms a part of this specification.

The nature of my invention consists in the construction of a nauticalsignal light cartridge which will leave a line or path of tire when theprojectile is shot into the air, as will be hereinafter more fully setforth.

In the annexed drawing, which fully illustrates my invention, the figurerepresents a central vertical section of my improved cartridge.

A represents a hollow cylinder, of wood, paper, or other suitablematerial, and of any desired dimensions. The bore of this cylinder ismade tapering, as shown, and contains a composition, B, which isslow-burning and scintillating.

At the end of the cylinder A is placed a disk, C, of hard wood or othersuitable material, holding the fulminate a.

The other end of the cylinderA is made concave to receive a ball, D, ofcolored-Ere composition, and this ball is surrounded by or inclosedwithin a coating, b, of meal-powder. The Vwhole is then inclosed withina shell or casing, F, leaving a chamber, G, for gnnpowder'.

In this signal-light it will thus be seen that I have a cylinder filledwith comparatively slowburning pyrotechnic composition, which is adaptedtov leave a line or path of fire when the projectile is shot into theair. rlloone enqd of this cylinder is attached a pyrotechniccomposition, D, for colored fire, and to the other end is attachedfnlminating material c, which will explode by percussion.

The outside case' or wrapper, F, may be of paper, cloth, or othermaterial suitable for the purpose.,

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-` The combination of the hollowcylinder A, less in diameter than the outer wrapper, the pyrotechniccompositions lB D, disk C, with fulminate a, and the outer case orwrapper, F, substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing as my own I have hereto afxed mysignature in presence of two witnesses.
